“Extended time” procedure 71
Step 37
The Daniel Senior Orifice Fitting is now ready for measurement.
4.3.2 “Extended time” procedure
This procedure is for the grease-assisted slide valves when the procedure takes over 15 minutes.
However, it is acceptable for soft-seated valves. For Seniors equipped with an O-Ring (10E) soft
seated valve, the operator may employ either the “QUICK CHANGE” procedure or the
“EXTENDED TIME” procedure. However, for the Seniors equipped with a grease-assisted slide
valve, the “QUICK CHANGE” procedure may be used only if it can be finished in less than 15
minutes.
